When the several members have been placed together, they are held in assembled position by the locking nut 26, and the curvature of the blade is adjusted by the application and adjustability of said locking nut 26 placed on the post 14:.

The top lnember is equipped with an up turned end 27 to which is pivotally connected an adjustable loop construction 28 consisting of two members 29 and 30, the free end of the member 29 carrying a loop 31 and through it is passed the free end of the member 30. By this arrangement the arms comprising the loop 28 can be spread or closed to accommodate the thickness of the finger to be inserted therein, and by means of the pivotal arrangement, the proper angle may be attained to suit the shaving position desired by the user.

In operating the razor, the user grips the finger grip 22' between the thumb and forefinger, and then inserts one of the other fingers into the loop 28, then by parting and closing the fingers, a reciprocating action is imparted, and when the razor is applied to the face, it creates a cutting effect by means of this reciprocating movement which is now void in all present standard safety razors, as their method is of the hoeing or scraping effect.

This razor has a unique principle, it is compact and easy to manipulate, and has a smooth cutting action.

Having fully described my invention what I claim, is:

1. A reciprocating razor comprising a base member, a center post and a lug formed thereon, the under surface of said base member provided with parallel curvilinear grooves, a razor blade positioned on the base member and supported by the post and stud, a slotted sliding member positioned on the razor blade and guided by the post and stud, an upturned finger grip formed on the end of said sliding member, a top member positioned over the sliding member, its side edges bent downwardly and formed into teeth, an adjustable loop member formed on the top member, and a lock nut positioned on the post for holding the parts in assembled position, substantially as specified.

2. A razor of the character described comprising a slightly concavo-convex base member, a razor blade seated on the concave surface of said base member, an elongated centrally slotted sliding member positioned on the razor blade, a pair of slides formed on the under surface of the sliding member and designed to rest on the blade, an upturned finger grip formed on one end of the sliding member and to be gripped between the thumb and forefinger, a top member positioned over the sliding member, an adjustable loop member connected to one end of the top member, said loop arranged to accommodate the insertion of either the third, fourth or little finger of the same hand, and a lock nut positioned on a post formed on the base member for holding the several parts in assembled position, substantially as specified.

3. A razor of the reciprocating type comprising a base member, a sliding member, and a top member, a razor blade firmly positioned on the base member, a post and stud formed on the base member and by which the blade is held rigid, the sliding member arranged to slide between the blade and top member its movement limited by an elongated slot formed in said sliding member, a finger grip formed on one end of the sliding member and to be held between the thumb and fore-finger, an adjustable loop attached to one end of the top member and in which may be inserted either one of the third, fourth or little finger of the same hand, the reciprocatory movement being accomplished by the closing and spreading of the fingers, and a lock nut for holding the assembled giedmbers in position, substantially as speci- 4. A reciprocating action safety razor comprising an upper member its sides provided with teeth, an adjustable loop formed on one end thereof, a reciprocating member, a finger grip formed on one end thereof, a base member, a double edge razor blade positioned between the reciprocating and base members, action imparted to the razor by spreading and closing the fingers at the same time gripping the finger grip and loop, and a lock nut for holding the members in assembled position, substantially as specified.

In witness whereof I-have hereunto set my hand this 9th day of Oct., 1929.

JACOB H. SCHUSTER.
